    Background and Objectives: The objectives of this study were to investigate the effectiveness of the applied laparoscopic urology course using a validated checklist and to determine any differences in laparoscopic skills achieved by the participants at the end of the course period based on whether they began their training in a dry or wet laboratory. Methods: To facilitate the mastering of challenging laparoscopic skills by urologists, a unique 3-day mini-training program was established at the Gulhane Military Academy of Medicine, Surgical Research Center, Ankara, Turkey. Only 30 trainees were accepted in each course, and they were divided into 3 subgroups. The primary outcome of the study was the changes in the performance and task accomplishment duration of the trainees at the beginning compared with the end of the course. The secondary outcome was any differences in the basic skills of the trainees based on whether they started their training in the dry or wet laboratory. Results: The overall laparoscopic skills, which were evaluated by use of a standardized laparoscopic suturing task score, significantly improved (18.8 to 26.0, P < .001), and the time needed for task accomplishment decreased throughout the course (9.5 minutes to 5.25 minutes, P = .002). With respect to the course design, laparoscopic skills scores and the times needed for task accomplishment showed no statistically significant changes at the end of the course despite the fact that the trainees had started their training at different stages. Conclusion: The applied short-term laparoscopy course was shown to be an effective format particularly for achieving laparoscopic skills in which suturing and knotting are essential. This is mainly achieved through close cooperation in dry and wet laboratories.

    Objective: In this multicenter prospective study, we aimed to evaluate the use of holmium:yttrium aluminum garnet laser during retrograde intrarenal surgery for kidney stones and the relationship between laser-related parameters and procedure-related perioperative parameters. Material and methods: The 769 patients whose laser setting parameters (fiber thickness, number of shots, frequency (max.), laser power (max.), and total energy) were completely registered were included in this study program. The intraoperative ureteral lesions were evaluated using postureteroscopic lesion scale (PULS) scores and the postoperative complications with the modified Clavien-Dindo classification system. Results: The maximum levels of laser power and the frequency were used in the middle calyceal stones; the value of total energy consumed was found to be higher gain in cases with multiple stones (all parameters P < .05). There was a significant positive correlation among (mean number of shots [P < .001, r = 0.46], frequency [P = .009, r = 0.1], maximum power [P < .001, r = 0.11], total energy [P < .001, r = 0.25]), anesthesia time (P < .001, r - 0.42), surgery time (P < .001, r - 0.47), and stone size. The mean number of shots increased (P < .001, r = 0.25), and the frequency level decreased (P < .001, r = -0.17) significantly with increasing Hounsfield unit (HU) values. Again, the mean number of shots and maximum laser power increased in correlation with the increasing hospitalization time (P = .004, r = 0.09 and P = .02, r = 0.07, respectively). In addition, it was observed that higher laser subparameter values and thicker fibers were used in PULS grade 2. Conclusion: As the stone size and HU values increased, laser-setting parameters were found to show significant variability. The increase in different parameters of the laser setting was found to be associated with longer anesthesia time, surgery time, and hospitalization period and increased risk of local trauma with PULS grade.

    Retrograde intrarenal surgery of renal stones: a critical multi-aspect evaluation of the outcomes by the Turkish Academy of Urology Prospective Study Group (ACUP Study)
    (Springer, 2021) Guven, Selcuk; Yigit, Pakize; Tuncel, Altug; Karabulut, Ibrahim; Sahin, Selcuk; Kilic, Ozcan; Balasar, Mehmet
    Aims To outline and evaluate the incidence, management and follow-up of the residual fragments (RFs) following retrograde intrarenal surgery (RIRS) of renal stones by the Turkish Academy of Urology Prospective Study Group (ACUP Study). Methods Following the ethical committee approval, 15 centers providing data regarding the incidence, management, and follow-up of RFs after RIRS were included and all relevant information was recorded into the same electronic database program () created by Turkish Urology Academy for Residual Stone Study. Results A total of 1112 cases underwent RIRS for renal calculi and RFs were observed in 276 cases (24.8%). Of all the parameters evaluated, our results demonstrated no statistically significant relation between preoperative DJ stenting and the presence of RFs (chi 2 (1) = 158.418; p = 0.099). RFs were significantly higher in patients treated with UAS (82 patients, 29.3%) during the procedure compared to the cases who did not receive UAS (194 patients, 23.3%) (chi 2 (1) = 3.999; p = 0.046). The mean period for a secondary intervention after RIRS was 28.39 (+/- 12.52) days. Regarding the procedures applied for RF removal, re-RIRS was the most commonly performed approach (56%). Conclusions Despite the reported safe and successful outcomes, the incidence of RFs is higher, after the RIRS procedure particularly in cases with relatively larger calculi. Such cases need to be followed in a close manner and although a second flexible ureteroscopy is the treatment of choice for fragment removal in the majority of these patients, shock wave lithotripsy and percutaneous nephrolithotomy may also be preferred in selected cases.
